Police told KCCI a concert with King Louie & Twista was wrapping up at 301 Ashworth Rd. about 2 a.m. As a couple hundred people were leaving, police conducting traffic control heard the sound of a gun shot.

They responded immediately to find a man who had been shot in the abdomen. He was taken to a hospital.

Daroyce Garnell Mills, 24, of Burnsville, Minnesota, was the man shot, police say. He is listed in critical condition at a metro hospital.

Witnesses told police the shooter fled the area. No arrests have been reported.

Neighbors took to their windows to grasp the striking scene overnight.

"It was really bad up there. I just watched by the window and saw a lot of policeman and it was very crowded," said Rebeca Rodriquez.

She said there's a need for more control in the neighborhood after two people broke into her car after concerts.

"The two times that happened there were concerts," said Rodriquez.

"It doesn't surprise me. You get different people there, a lot of people from different walks of life depending on the concerts there," said Jacob Vander Ploeg."We're hoping that if somebody saw something or recorded something on a phone that they will come forward," said Sgt. Brent Kock, spokesman for West Des Moines police.
